Put Auto Scaling Policy

emr_put_auto_scaling_policy

R Documentation

Creates or updates an automatic scaling policy for a core instance group or task instance group in an Amazon EMR cluster

Description

Creates or updates an automatic scaling policy for a core instance group or task instance group in an Amazon EMR cluster. The automatic scaling policy defines how an instance group dynamically adds and terminates Amazon EC2 instances in response to the value of a CloudWatch metric.

Usage

emr_put_auto_scaling_policy(ClusterId, InstanceGroupId,
  AutoScalingPolicy)

Arguments

ClusterId

[required] Specifies the ID of a cluster. The instance group to which the automatic scaling policy is applied is within this cluster.

InstanceGroupId

[required] Specifies the ID of the instance group to which the automatic scaling policy is applied.

AutoScalingPolicy

[required] Specifies the definition of the automatic scaling policy.
